I have a Powerconnect 6248P with POE not working. I used the show poe-firmware-version and it returned "Failed to get firmware image version details. I have another 6248P that will show the firmware version fine.
I did find this Dell POE support document where it talked about a way to download the POE controller firmware but it does not show how to do so. Has anyone else run into this problem? Below is the part of the dell document
POE CONTROLLER FIRMWARE UPGRADE
The POE firmware is part of the switch operational code. When the switch boots up, the POE Controller's firmware is checked. If the version received is different from the one present with the switch code, or if the firmware in the POE controller is corrupted or is not present, a firmware upgrade (or download, as the case may be) will be done.
